Yeah, anecdotally the internet agrees with that a soulslike is not survival horror 
I’ve talked about this genre in other topics (Forsaken Denizen - #15 by severedhand and others) and being an old survival horror head, I admit it’s hard to guess how people interpret the survival horror label these days if they weren’t around, or at least into the games at some point, that were characterised by that label as almost a brand before both that style and the brand name fell out of mainstream popularity.
In a sense, it’s the qualities of the games that possessed that brand originally that define “survival horror” rather than either of the meanings of the words in the brand label. I tested Forbidden Denizen (EDIT— FORSAKEN Denizen! I’ve been doing this ever since I met the game, typing Forbidden instead of Forsaken 
I assume because of Forbidden Siren) and it is laced with both broad and specific (i.e. sometimes quoting) elements from those original generation survival horror games. That’s why its tagline makes good sense.
Most players during IFComp have been finding it skewing not-too-difficult, which is potentially the most at odds element with the genre as a whole, and certainly at odds with the ghost of the idea of the genre. Particularly for the folks who were never into it. But even if it’s unusual on this axis, there is that long and majority checklist of specific OG survival horror boxes it ticks that home it there. People who don’t come from that survival horror history already like the game a lot now. You or they may find it’s one of those games that has something extra to offer by opening a window onto other games and histories.
